I am using a usb flash drive. I have already watched many videos and I can mod the file fine. Once I bring it back to the xbox I cannot get it to work with my online profile. I have tried logging in with the modded account then trying to play live, then i sign in with my legit live account and the name hasn't changed. I've done that many different ways that different videos tell you, but none of them work for me. Any help will be greatly appreciated.
